MP573 Assembly guide – Main PCB, A side
7. A side
Turn the board over, A side up. Make sure all the B side component leads have been cut as short as
possible.
8. Diodes
Add D3, D4, D6 to D9. Use a lead forming tool to bend the leads at 0.4”.
Warning
: Make sure to respect the direction of the diodes which is marked by a ring on the component
and a double line on the PCB marking.
9. Horizontal resistors
Add R1, R2, R17, R18, R21, R24, R26, R27, R29 to R37, R39 to R58.
Control the resistor values with a digital multimeter. Bend the leads at 0.4” with a lead forming tool,
except for R26 and R47 which are bended at 0.6”.
10. Integrated Circuit
Insert U3 and solder. You will need to bend the pins slightly inwards before inserting. Make sure you are
not charged with electrostatic electricity before handling the IC (or remove your shoes).
Warning
: Make sure to respect the IC direction, marked by a notch. Do not use a socket because it
would be to high for the Di01 board.
11. Test pins
Solder the 5 test pins TP1, TP2, V+, TP4 and 0V as well as 2 additional pins, used for mechanical
strengthening near CN1.
These pins are inserted from the top PCB side, long tail up. After soldering, cut flush on the solder side.
